Applications
The GBU8D-E3/45 bridge rectifier is designed for AC-to-DC power conversion in industrial power supplies, battery chargers, and motor drive front-end rectifier stages where a 200 V reverse voltage rating is required. Its isolated GBU package simplifies heatsinking and thermal management in equipment with multiple power rails or shared chassis ground planes. The 200 A peak surge current rating makes it tolerant of the inrush current spikes common during capacitor-input power supply startup.

Frequently Asked Questions
What breakdown voltage does the GBU8D-E3/45 bridge rectifier support?
The GBU8D-E3/45 has a minimum breakdown voltage of 200 V, making it suitable for rectifying AC line voltages up to approximately 140 V RMS (equivalent to a 200 V peak). It is commonly used in 100 V to 120 V AC mains rectification applications such as linear power supplies and battery charger input stages.
How much surge current can the GBU8D-E3/45 handle during power-up?
The GBU8D-E3/45 is rated for a non-repetitive peak forward current of 200 A, which handles the inrush surge that occurs when a capacitor-input power supply is first energized. For a typical 1000 µF filter capacitor, the initial charge current spike can easily reach tens of amperes, and the 200 A rating provides a large safety margin.
What forward voltage drop does the GBU8D-E3/45 introduce and how does it affect efficiency?
The maximum forward voltage drop of the GBU8D-E3/45 is 1 V per diode element. In a full-wave bridge configuration, current passes through 2 diodes simultaneously, resulting in a total forward voltage loss of up to 2 V. For a 12 V DC output, this represents about a 14% voltage loss, which should be accounted for in transformer secondary winding and regulation design.
In which power conversion applications is the isolated GBU package of the GBU8D-E3/45 most advantageous?
The isolated GBU case connection of the GBU8D-E3/45 electrically separates the mounting tab from all 4 diode pins. This allows the bridge rectifier to be bolted directly to a chassis heatsink without an insulating washer, reducing thermal resistance and simplifying mechanical assembly in AC-DC power supplies, motor drives, and UPS equipment operating at or below 200 V reverse blocking.
